Abstract

All-fiber based devices for third harmonic generation in the ultraviolet range are highly desirable. Using a fundamental wavelength of 1.06 mu m as an example, we show numerically how the phase-matching condition for third harmonic generation can be achieved between an index-guided fundamental HE11 mode for the infrared source and a bandgap-guided higher-order HE12 mode for the ultraviolet radiation in all-solid photonic crystal fibers. The fiber parameters are first determined by an analytical effective index model and then improved by numerical calculations.
